Demattia flex tester.

The DFT2100 Demattia flex tester is said to be ideal for testing fatigue, breakage or crack growth in rubber, plastics, exotic composites and other materials. The DFT2100 is used for such diverse products as tires, belts and hoses, laminates, athletic equipment, aerospace and automotive parts, medical products, shoe soles and more. With 20 stations, the DFT2100 simultaneously flexes as many as 20 product samples for up to 10 million cycles, and has the ability of variable speed testing from 30 to 300 cycles/minute. The accelerated testing can save days in determining a product's ability to withstand repeated flexing, according to the company. An unusual feature is said to be a temperature chamber which allows testing from -100[degrees]C to +150[degrees]C. The temperature controller was designed to precisely control the temperature while also controlling the test speed. Several different products can be simultaneously tested. Fixed distances range from 0.25" to 4" (6 to 101.6 mm). The DFT2100 can be pre-set to as many as 10,000,000 cycles and then digitally displays either the number of cycles remaining in the test or the number that have been completed. The DFF2100 can be used in testing materials to ASTM, ISO, DIN, BS, JIS and other U.S. and international standards. (Benz Materials Testing, Instruments)
